Lactones 192-199 cytochrome P450 family 24 subfamily A member 1 Homo sapiens 0-7 17646648-0 2007 Single A326G mutation converts human CYP24A1 from 25-OH-D3-24-hydroxylase into -23-hydroxylase, generating 1alpha,25-(OH)2D3-26,23-lactone. Lactones 131-138 cytochrome P450 family 24 subfamily A member 1 Homo sapiens 37-44 17646648-1 2007 Studies of 25-hydroxyvitamin D(3)-24-hydroxylase (CYP24A1) have demonstrated that it is a bifunctional enzyme capable of the 24-hydroxylation of 1alpha,25-(OH)(2)D(3), leading to the excretory form, calcitroic acid, and 23-hydroxylation, culminating in 1alpha,25-(OH)(2)D(3)-26,23-lactone. Lactones 281-288 cytochrome P450 family 24 subfamily A member 1 Homo sapiens 50-57 16816472-7 2006 In addition to the C-24 oxidation pathway, human CYP24A1 catalyzed also C-23 oxidation pathway to produce 1alpha, 25 (OH) (2)D(3)-26, 23-lactone. Lactones 137-144 cytochrome P450 family 24 subfamily A member 1 Homo sapiens 49-56
